NEW ORLEANS – The Saints may not have a lot of money to play with, but they realize that the odds are against them if they don't make some moves to improve a few of their weaker areas.

Remember that during the 2014 free agency season the Saints were said to be cash-strapped and somehow they found a way to pluck out a premier free agent in Jarius Byrd.

This year, if they go shopping when the market opens on March 10, there are four guys who could be on their shopping list.

- The team desperately needs a corner to play opposite of Keenan Lewis. And while they could try to fill the need through the draft, their best and most realistic option would be to dip into the free agency market as it is flush with quality name veterans. Houston's Kareem Jackson was a former first round pick out of Alabama in 2010. Jackson's career has been marked by inconsistency, which is why he won't command top dollar. Nevertheless, after big seasons in 2012 and 2014, he appears to have blossomed into one of the NFL's top press-man corners. Moreover, at 27, he's entering the prime of his career and would be a good fit in Rob Ryan's schemes.

- Should Jackson be scooped up or his price be too steep, the Saints could turn their attention to the 49ers Perrish Cox. The Saints managed just 10 interceptions in 2014. Cox had 5 himself. When you add 18 passes defensed, Cox is clearly has a nose for the ball, something the Saints desperately need more of.

- The interior of the Saints offensive line was problematic in 2014 so the team could choose to bring back veteran center Brian De La Puente, who is very familiar with the organization. De La Puente was the starting center during Drew Brees' three consecutive 5,000-yard passing seasons from 2011 to 2013.

On the defensive side of the ball, Miami's Jared Odrick would be a huge get. At 6'5 and 300 pounds, he's capable of playing anywhere on the defensive front and is considered one of the most versatile defensive linemen available. Even more impressive is his durability. He hasn't missed a game in more than four years, during which he has recorded 103 tackles, 16.5 sacks, 3 forced fumbles and an interception. He's another 27-year-old entering the prime of his career and the Dolphins are currently working on a deal to keep him in Miami. But if he does manage to get free, there will be no shortage of interested parties.
